The PCM turns shift solenoid valve A OFF, and shift solenoid valve A covers the port of shift solenoid valve A pressure
(SA) to the shift valve A. Shift solenoid valves B and C keep OFF. The shift valve A is m o v e d to t h e left side to switch
the port of line pressure (5B), CPC A pressure (5A) (5L) leading to the 4th clutch, and 3rd clutch pressure (30) releasing
3rd clutch pressure. CPC A pressure (5L) changes to line pressure (5L) and 4th clutch pressure (40) is changed to line
pressure mode, and the 4th clutch is engaged w i t h the line pressure mode. The 1st clutch is also engaged, but no
power is transmitted because of the one-way clutch.
NOTE: W h e n used, " l e f t " or " r i g h t " indicates direction on the hydraulic circuit.
